Email this article Modeling And Simulation of An Advanced Step Up Converter For Low Voltage Energy Harvesting By Using Fuzzy Logic Controller
Abstract
This paper presents a direct AC-DC power electronic converter topology and it is proposed for efficient and maximum energy harvesting from low voltage inertial micro generators. To process the positive and negative half cycles of the ac input voltage, this power converter consists a boost converter and a buck-boost converter respectively. The analysis of this AC-DC step up converter is to obtain the relations between power, circuit parameters, and duty cycle of the converter. The ac-dc step up converter using PI-controller should not give the better THD value. For better performance the present model is proposed with the fuzzy logic controller. Using this converter maximum energy harvesting is implemented effectively. Simulation results by using MATLAB software are found to be quite satisfactory to suppress the total harmonic distortions with improvement in performance.
